Paper on how vertical wind shear impacts surface winds in hurricanes released online in Monthly Weather Review

Summary: Scatterometers are instruments on aircraft or satellites that are used to measure wind speed and direction at the ocean surface. In this follow-up to a 2016 study, the surface wind in tropical cyclones around the world are studied using a large set of measurements from 2000 to 2011. The impact of tropical cyclone intensity, […]

Two part paper on convective bursts in hurricanes published in Monthly Weather Review

These two papers analyze extreme upward air currents, called “convective bursts,” in hurricanes that have been believed to be important for hurricane intensification. We use the Weather Research and Forecasting (WRF) model to look at convective bursts in two hurricanes: Hurricane Dean from 2007 and Hurricane Bill from 2009. In the first paper, we study […]

Paper on accounting for the location of dropwindsondes during measurements released online in the Journal of Atmospheric and Oceanic Technology

Summary: Hurricane Hunter aircraft have been releasing instruments called dropwindsondes to measure pressure, temperature, moisture, and wind speed and direction in hurricanes for two decades. Data from dropwindsondes released near the storms have led to better forecasts of where they will go, but improvements to forecasts of how strong they will get have lagged. Part […]

Paper on a preliminary test of the impact of data from a new satellite published in the Marine Technology Society Journal

Summary:  The new National Aeronautics and Space Administration CYclone Global Navigation Satellite System (CYGNSS) measures wind speed on the ocean surface. Because hurricanes happen over oceans where other wind data are usually not available, these new observations may be useful in pinpointing their positions and intensities. This study examines whether CYGNSS wind information will improve […]

Book chapter on monitoring tropical cyclones with the Synthetic Aperture Radar published

  Satellite images taken from an instrument called the Synthetic Aperture Radar (SAR) that can see things on the earth’s surface that are about 100 m (300 ft) across are used study the wind in tropical cyclones. The SAR can see small swirls (called vortices) near the eye of the hurricane, small long, thin lines […]

Paper on forecast improvements due to dropsonde data from the Global Hawk aircraft published in Monthly Weather Review

Starting in 2010, the National Aeronautic and Space Administration and the National Oceanic and Atmospheric Administration have used the Global Hawk, an unmanned aircraft that can fly at 65,000 feet for 24 hours at a time, to make observations in tropical cyclones. The Global Hawk can release dropsondes that measure temperature, humidity, pressure, and wind […]
